The steps below should be followed in the order they appear. **Make sure the GitLab version is the same on all nodes.**
## Using Omnibus GitLab
If you installed GitLab using the Omnibus packages (highly recommended):
1. [Install GitLab Enterprise Edition](https://about.gitlab.com/install/) on the server that will serve as the **secondary** node. Do not create an account or log in to the new **secondary** node.
1. [Upload the GitLab License](../../../user/admin_area/license.md) on the **primary** node to unlock Geo. The license must be for [GitLab Premium](https://about.gitlab.com/pricing/) or higher.
1. [Set up the database replication](database.md) (`primary (read-write) <-> secondary (read-only)` topology).
1. [Configure fast lookup of authorized SSH keys in the database](../../operations/fast_ssh_key_lookup.md). This step is required and needs to be done on **both** the **primary** and **secondary** nodes.
1. [Configure GitLab](../replication/configuration.md) to set the **primary** and **secondary** nodes.
1. Optional: [Configure a secondary LDAP server](../../auth/ldap/index.md) for the **secondary** node. See [notes on LDAP](../index.md#ldap).
1. [Follow the "Using a Geo Server" guide](../replication/using_a_geo_server.md).
## Post-installation documentation
After installing GitLab on the **secondary** nodes and performing the initial configuration, see the [following documentation for post-installation information](../index.md#post-installation-documentation).
